Default Transmission replacement 5.7L V8

I have a 1995 Sierra 2500 5.7 V8 and it needs a new transmission.

Can I use a transmission from a 4.3L V6? I have the opportunity to pick one up real cheap and I can't find if it will work.

I'm not much of a mechanic but I have someone who will do the work for free if I can get the parts.

I wouldn't. Chances are, your truck has a 4l80 instead of a 4l60 that the V6 has. Just get the one you have rebuilt, you'll probably be better off.

Thanks for the reply! From what I could research that is what I thought

Major noobie to all this - what is a 4l80?

Well GM transmissions work like this. For your trucks, if it is an automatic, you have a four speed, Longitudinally, and 80 is the torque rating that your transmission is good for. I'm not sure exactly what 80 translates to in terms of torque capacity, but a 4L80 is stronger and different than a 4L60.

So on a 2500 truck, I'd venture a guess you have a 4L80 instead of a 4L60, but I could be wrong.

The 4l80E pan looks like this:


And the 4L60E looks like this:


Lay under your truck and see which one yours looks like.
